How do I save the output I have to a new text file?

I'm not sure exactly what's going on in your code.

But to write a variable to a file, you can use

with open('output.txt', 'w+') as new_file: new_file.write(variable) 

Note that the 'w+' will create the file if it doesn't exist, and will overwrite it if it does.

And if it's all the items in txt_list you want to write to that file, I don't think I'd join them first. Just use a for loop:

with open('output.txt', 'w+') as new_file: for item in txt_list: new_file.write(item) 

This would print every item in that list on a new line in the file.

txt_list = [] with open("X:\- Photogrammetry\Python to Correct DXF Colors\InvolvedPontiac.dxf", "r") as in_file: for line in in_file: line = line.rstrip() txt_list.append(line) Entity = 0 i = 0 while i < len(txt_list): if txt_list[i] == "ENTITIES": Entity = 1 if txt_list[i] == " 62" and Entity == 1: txt_list[i+1] = " 256" i += 1 Layer = 0 j = 0 while j < len(txt_list): if txt_list[j] == "LAYER" and txt_list[j+2] != " 7": Userinput = input("What color would you like for the layer " +txt_list[j+2] + "? Type 0 for black, 1 for red, 3 for green, 4 for light blue, 5 for blue, 6 for magenta, 7 for white, 8 for dark grey, 9 for medium gray, or 30 for orange.") txt_list[j+6] = " " + Userinput print ("The " + txt_list[j+2] + " layer now has a color code of " + Userinput) j += 1 with open('output.txt', 'w+') as new_file: for item in txt_list: new_file.write(item) print ('\n'.join(txt_list)
